Dear Dr. Stoddart:

Few coral species seem to use the asexual planula strategy, and even
those that have reported to do it are unlikely to use it all that often
(as population genetic studies have shown).  My answer was meant to be a
short generic answer and not a treatise to respond to every potential
caveat (this addresses also the comment about the accumulation of
mutations over time, which has been speculated about but not

Kind regards,

I'm sure there will be a number of replies pointing out that several
of coral also produce planulae asexually, such that clones can propagate
through planular dispersal & settlement.

Given the issue raised in clones like Dolly the sheep about aging
a more relevant measure of age of clones may by the number of mitotic
divisions since meiosis.
